Sturdy Box for PlusPlus

Combined container and 7x17 build plate for small plus plus like pieces (15x20mm kind i.e 4x4mm square interface) It is a good idea to test the fit with your printer with “3.9round3x2plusplus” first before printing the entire thing. I have tried it in PLA w. 0.15 layer height and it worked well for me. Just press some slightly kinked 1.75mm filament in for the hinges! Happy printing!
